What is the solution to the equation fraction 4 over 5 n minus fraction 1 over 5 equals fraction 2 over 5 n?
photoshop1234 [79]

Answer:

value of n = 2

Step-by-step explanation:

\frac{4}{5n}-\frac{1}{5}=\frac{2}{5n}

We need to solve the above equation.

Find Least Common multiplier from 5n, 5 = 5n

Multiply both sides of the equation by 5n

\frac{4}{5n}*5n-\frac{1}{5}*5n=\frac{2}{5n}*5n\\Solving:\\4 -n = 2\\

Now finding the value of n.

Adding -4 on both sides

4 -n-4 = 2-4\\-n= -2

Multiplying both sides by -1

n = 2

The value of n is 2.

We can verify by putting value of n in the given question.

\frac{4}{5n}-\frac{1}{5}=\frac{2}{5n}\\n=2\\\frac{4}{5*2}-\frac{1}{5}=\frac{2}{5*2}\\\frac{4}{10}-\frac{1}{5}=\frac{2}{10}\\\frac{2}{5}-\frac{1}{5}=\frac{1}{5}\\\frac{2-1}{5}=\frac{1}{5}\\\frac{1}{5}=\frac{1}{5}

So, value of n = 2

What is the product of the binomials below?
fgiga [73]

Answer:

\boxed{ \bold{  \huge{ \boxed{ \sf{6 {x}^{2}  + 23x + 20}}}}}

Option A is the correct option.

Step-by-step explanation:

\sf{(2x + 5)(3x + 4)}

Use the distributive property to multiply each term of the first binomial by each term of the second binomial

⇒\sf{2x(3x + 4) + 5(3x + 4)}

⇒\sf{6 {x}^{2}  + 8x + 15x + 20}

Collect like terms

⇒\sf{6 {x}^{2}  + 23x + 20}

Hope I helped !

Best regards!!

The area of a square is 1/4in^2 find the perimeter
Alex777 [14]

The sides must be 1/2 because 1/2 ^ 2 = 1/4. 1/2 + 1/2 + 1/2 + 1/2= 2 which will be your perimeter. If this is right could you possibly give me brainliest? Hope this helped.
